The Law on Metal Detecting in Ireland

Details on the use of metal detectors to look for archaeological objects and frequently asked questions on what to do with finds.

Advice to the Public from the Minister for Arts, Heritage and the Gaeltacht and the National Museum of Ireland on Use of Metal Detection Devices in Ireland

The unauthorised use of metal detectors to look for archaeological objects is against the law.

Such usage is subject to severe penalties, including imprisonment and/or fines. The categories of objects that are most commonly located by metal detectorists in Ireland, such as coins, tokens, buttons, clothes fasteners, thimbles, keys, seals, weights, strap ends and belt mounts, all fulfil the definition of ‘archaeological objects’ which may only be searched for under license.

It is advised therefore that persons do not engage in general searches for lost or buried objects as to do so may place them at risk of prosecution and endanger the archaeological heritage.

Answers

Unless you have a licence from the Minister for Arts, Heritage and the Gaeltacht, it is also an offence to dig or excavate for the purpose of searching for archaeological objects, or anything of archaeological interest, even though you may not be using a metal detector.

The penalty for this offence is a fine of up to €126,972 and/or up to 12 months imprisonment.

Unregulated and inappropriate use of metal detectors causes serious damage to Ireland’s archaeological heritage. Unsupervised recovery of archaeological objects by untrained and unlicensed users of metal detectors can greatly diminish, or can entirely eliminate any knowledge or research value that might be gained from a particular discovery.

Archaeological objects must be excavated in a structured scientific manner, with careful recording of their association with other objects, structures, features and soil layers. Failure to expertly record the context from which an object has been removed results in an irreplaceable loss of knowledge of the past.

Random searches with metal detectors cannot determine whether a find is of archaeological importance, or if it is a recent discard. The result in either case is that the soil is greatly disturbed and any non-metallic evidence and objects are likely to be destroyed.

Archaeologists are highly trained professionals who are closely regulated by licence and by public policy and codes of practice.

The information and regulatory provisions outlined here do not in any way affect those who may find archaeological objects by chance - for example in the course of farming activity - provided the find is reported in accordance with the advice in Paragraph 6 above.

It is normal practice to pay rewards to finders of archaeological objects discovered in legitimate circumstances and reported to the National Museum of Ireland.

To prevent damage to our archaeological heritage by the unauthorised use of metal detectors, the National Monuments Acts 1930 to 2004 regulate the use of metal detectors for archaeological purposes throughout the State of Ireland and its territorial seas.

Unless you have formally applied for and received a Detection Consent from the Minister for Arts, Heritage and the Gaeltacht under the National Monuments Acts, it is against the law

to be in possession of a detection device in, or at the site of, a monument subject to a Preservation Order, or a monument in the ownership or guardianship of the Minister or a local authority, or a monument entered in the Register of Historic Monuments, or a monument included in the Record of Monuments and Places or a restricted area;

to use a detection device for the purpose of searching for archaeological objects anywhere within the State or its territorial seas.

The penalty for an offence in relation to the above is a fine of up to €63,486 and/or up to 3 months imprisonment.

Anyone using a metal detector in contravention of the above restrictions and who, following detection of an object, digs to retrieve an archaeological object without an excavation licence, may be guilty of an additional offence under the terms of the National Monuments Acts.

Under the National Monuments Acts 1930 to 2004 it is illegal to promote, whether by advertising or otherwise, the sale or use of detection devices for the purpose of searching for archaeological objects.

The penalty for those found guilty of this offence is a fine of up to £1000 (or the euro equivalent).

As a general rule, the Minister for Arts, Heritage and the Gaeltacht will not grant consents for the use and/or possession of metal detectors except to suitably qualified archaeologists or persons who will be working under professional on-site archaeological supervision.

Before a Consent to use a metal detector is issued, the applicant will have to make clear that the use of the device is in accordance with best archaeological practice.

This is achieved through the submission of a detailed method statement setting out the proposed work programme for assessing a site and achieving the greatest possible level of archaeological knowledge from the work undertaken.
